I think it is more likely the more children you have i think-but that usually happens because you are older rather than the number of children you have had iyswim? (however not quite in my case- i was 27 with first set and 30 with second set.

Fraternal twins is meant to run in families-but not in my case....however every 'run in family thing' has to start somewhere!

Yes I have twins, DD4 and DD5. I had no idea until nearly half way through my pregnancy as I didn't go for an early scan (this was 12 years ago). The pregnancy itself was not so very different from any of the others until near the end when I was huge, but then they were 7lb 6oz and 7lb 12oz and I'm only little!

I am five, all single births, but DS1 should have been a twin (I lost his twin at 6/7wks).

there are many twins on my side of the family, and I would have loved having twins, but not to be.

I nannied twin boys tho before having mine, and I have to say, (pregnancy bit ignored here as I obviously cannot comment), I found twins far far easier than single babies.....when I had DD1 I was at a acomplete loss as to what to do with 'just' one baby!!

so much so, I went back to the family and to the twins when DD1 was 5wks old, I missed to 'two-someness' of it all.
